The widest range of production polishers utilizing Seikoh Giken’s proprietary turntable design. With the exclusive rotation-revolution mechanism, polishing films and polishing processes, and with over two decades of connector polishing expertise all contribute to the highest quality optical performance U.S.Pat. No.4,979,334 / 5,351,445 / 6,165,055.



The SFP-560A fiber polisher is Seikoh Giken’s newest premium production polisher and the first in the marketplace to incorporate the patent pending Dynamic Pressure Control (DPC) pressurization system. The unique DPC pressure technology offers a mass production platform incorporating highly stable, widely variable precision pressure control to the polishing Turntable. The pressure is applied from the bottom to the top. Moreover, SG’s advanced micro machining design guarantees polishing with perfect parallelism between the polisher's turntable and the rigidly clamped polishing holder by the 4 corners.

Combining proprietary bottom-up pressurization, precision speed & pressure control and rigid fixture parallelism, the SFP-560A series – while in DPC mode - realize epoxy removal of multi-fiber ferrule done by the SFP-560A polisher and perform multi-fiber polishing similar in simplicity to standard single fiber connector polishing.

Additional SFP-560A features include1) Programmable polishing process up to 60 processes,
2) Four (4) multi-timers for manual polishing operation,
3) High Contrast, waterproof LCD Display with multi-language programming operation (ENG-CHN-SPN-JPN),
4) Selectable, password protected programming and operations modes for both administrators and users
5) Operation and Maintenance Data metrics transfer via USB interface.



This model also offers excellent production throughput capability with up to 24 ferrules polishing simultaneously. Extremely versatile, the OFL-15A can polishing both connectors, ferrules and MT ferrules. It features a LCD touch panel for easy programming of various connector polishing processes which offers ease of operation. Additionally, it features an active polishing pressure control through it's closed-loop load-cell sensor and stepping motor. This combination provides excellent polishing results while exceeding industry specifications for geometry performance.


The SFP-550S3 polisher series is Seikoh Giken's top of the line mass production model developed under our recently introduced "Ez-Maintenance and High Duty Cycle" concept. Compared to the previous SFP-550 series, there is dramatic improvement in ease of maintenance and machine durability for mass production work zones. SG estimates maintenance cost reduction of nearly 90% (per our internal test) can be achieved compared to older generation polishers. It features a full function, programmable LCD touch panel for installation and modification of various polishing processes allowing unlimited customization of process detailed parameters. Additionally, it features a slow start function, user controlled, programmable turntable speed and voltage-free power input for world-wide versatile installation.

The most notable feature is our unique auto polishing time distribution which allows the polishing time to gradually change after each use of the polishing film. It provides stable grinding force for uniform endface geometry and extends film service life. Developed for use in high volume mass-production environments where critical geometry performance is required.

Polishing holders, films and pads are compatible among all 550 (120A) series.


The SFP-550E3 Polisher Series is Seikoh Giken's mid-range polisher offering a competitive priced, high volume programmable mass production model under our recently introduced concept "Ez-Maintenance and High Duty Cycle" series. Compared to the previous SFP-550 series, there is drastic improvement in ease of maintenance and machine robustness that has achieved reduction in maintenance cost (90% less per our internal test).

This new model SFP-550E3 features Multi Timer on LCD Touch Panel (4 timers). In addition, it features simplified polishing process programming (8 steps each x 12 processes). Polishing speed is variable from 70rpm to 200rpm for revolution and rotation speed is automatically adjusted as per revolution speed.

A notable feature of this polisher series provides the option to add a Center Pressure Module, which converts this machine to be used as an advanced multi fiber polisher. (Note: the Center Pressure Module can be mounted to all SFP-550 series).

Polishing holders, films and pads are compatible among all 550 (120A) series.



The SFP-550C Polisher Series is Seikoh Giken's entry level mass production model. The 550C series model was also developed under the recently introduced concept of "Ez-Maintenance and High Duty Cycle" series. And, compared to the previous SFP-550 series, there is dramatic improvement in the ease of maintenance and machine robustness that has achieved reduction in maintenance cost (90% less per our internal test).

The addition of the high speed turntable technology allows the SFP-550C model to increase productivity by more than 20% (according to our internal test) over previous entry level polishers.

All Seikoh Giken polishing holders come equipped with the proprietary IPC (Individual Pressure Control) system that provides even pressure to each ferrule regardless of it's protrusion length while achieving stable and high-quality output.

Efficient large scale mass production lines focused on cost/production savings can be established by installing this combination of polishing machine and IPC holder for each polishing step.


This model is intended for light production capacity. The SFP-70D provides 6 axis simultaneous polishing and can be operated on AC or DC power for field use. Optional adhesive heaters are also available which can be attached to the polishing machines.


This model provides 2 axis simultaneous polishing at competitively low cost and is most suitable for light production environments like field termination and laboratory use.
